[0011] Preferably, the first threaded through hole and the second threaded through hole are symmetrically arranged on the fourth steel plate.

[0012] Preferably, the centers of the first threaded through hole and the second threaded through hole are consistent with the center of the bearing seat in the thickness direction.

[0013] Preferably, a first rib plate and a second rib plate are provided on the back of the fourth steel plate to increase the strength of the bracket in the horizontal direction.

[0014] Preferably, the first steel plate and the second steel plate are welded and fixed on the support.

[0015] Preferably, when adjusting the axial position of the bearing, the adjustment devices are used in pairs and are distributed on both sides of the axial direction of the bearing seat.

[0016] Preferably, when adjusting the axial position of the bearing, the axial center position of the bearing is adjusted by an adjusting bolt of the adjusting device.

[0026] The present invention is further described below in conjunction with specific embodiments. It should be understood that these embodiments are only used to illustrate the present invention and are not used to limit the scope of the present invention. In addition, it should be understood that after reading the content taught by the present invention, those skilled in the art can make various changes or modifications to the present invention, and these equivalent forms also fall within the scope defined by the claims attached to this application.

[0027] like Figure 1 As shown, the utility model provides an embodiment of a device for adjusting the axial center position of a bearing, including a bracket 1, an adjusting bolt 2, and a locking nut 3. The bracket 1 is formed by welding a plurality of steel plates and ribs. The first steel plate 11 and the second steel plate 12 on the bracket 1 are symmetrically arranged to play a supporting role. The third steel plate 13 on the bracket 1 is placed horizontally and welded to the first steel plate 11 and the second steel plate 12, serving as a connection platform between the upper steel plate and the ribs and the lower supporting first steel plate 11 and second steel plate 12. The fourth steel plate 14 is perpendicular to the third steel plate 13, and the shape of the fourth steel plate 14 is specifically designed according to the width and height position of the specific bearing base. The fourth steel plate 14 is provided with two symmetrical threaded through holes, including a first threaded through hole 101 and a second threaded through hole 102, the center of the threaded through hole is consistent with the center of the thickness direction of the bearing base, the first threaded through hole 101 and the second threaded through hole 102 point to the two ends of the bearing base respectively, and the back of the fourth steel plate 14 is provided with a first rib plate 15 and a second rib plate 16, and the first rib plate 15 and the second rib plate 16 are used to increase the strength of the bracket in the horizontal direction; the adjusting bolt 2 first passes through the locking nut 3, and then the locking nut 3 is screwed to the top of the adjusting bolt 2, and then the adjusting bolt 2 and the locking nut 3 are screwed together into the first threaded through hole 101 and the second threaded through hole 102 on the bracket.

[0028] When adjusting the axial position of the bearing, two sets of adjustment devices are usually required to work simultaneously. The two sets of devices are respectively placed on both sides of the center of the bearing axis. The first steel plate 11 and the second steel plate 12 of the bracket 1 are fixed to the support 4 of the bearing seat 5 by welding or bolting. In this example, it is fixed by welding.
